Abstract: 730,564. Jet propulsion plant. NAPIER & SON, Ltd., D. Jan. 29, 1953 [Feb. 7, 1952], No. 3279/52. Class 110 (3). A jet propulsion power unit of the kind in which the motive power is derived at least mainly from a single liquid comprises a reaction chamber and control means for varying simultaneously and correspondingly the effective cross-sectional area of the propulsion nozzle and the setting of the apparatus supplying the fuel to the reaction chamber in such manner as to maintain within the reaction chamber for any-setting of the control means a predetermined pressure and temperature suited to operational requirements and such that each particle of fuel remains for a sufficient time and under adequate temperature conditions within the reaction chamber to ensure satisfactory completion of the reaction in such particle. In the construction shown the reaction chamber A is provided with a main propulsion nozzle B in which a bullet C<SP>3</SP> moves under the control of the piston G of a hydraulic servo device to vary the effective cross-section of the nozzle. The control valve of the servo device may be set by a control lever G' and is adjusted in accordance with atmospheric pressure by a bellows-type evacuated capsule H. A gas turbine K<SP>1</SP> fed from the reaction chamber through a passage K<SP>2</SP> drives centrifugal pumps J<SP>3</SP>, J<SP>5</SP> which pump fuel round the outside of the reaction chamber to the injection devices D<SP>2</SP> and through control valves to injection devices D3. A metering orifice O arranged in the fuel supply line is controlled by a servo device which is also controlled by the lever G' through a bellows O<SP>4</SP>; the fuel may be the working fluid for both servo devices. The exhaust of the gas turbine K<SP>1</SP> passes through passage K<SP>5</SP> to an auxiliary propulsive nozzle K<SP>6</SP>, and if desired a control device Q may be provided to reduce the flow through passage K<SP>5</SP> if the fuel pressure gets too high. The delivery passages of the fuel pumps J<SP>3</SP>, J<SP>5</SP> communicate with the storage space of a pressure accumulator M; the accumulator may be connected through a valve to an air bottle B<SP>4</SP> so that the pressure can be augmented by opening the valve. The accumulator is connected through a non-return valve M<SP>6</SP> with a source of priming fuel (not shown), so that priming fuel can be delivered to the igniter passage F by a pipe F<SP>3</SP> to initiate the reaction when the cartridge starter Fl is fired. The gas turbine K<SP>1</SP> is provided with two inlet valves P<SP>2</SP> and <SP>p3</SP> so that its power may be controlled as required. All the valves are controlled electrically from a master controller R.

Title: Improved process of and apparatus for cracking hydrocarbons
IPC: C10G9/40
Filed: 1927-02-07
Abstract: 278,235. Jansen, H. J. Feb. 7, 1927. Hydrocarbons, cracking; evaporating by contact with hot liquid. - In cracking hydrocarbons by passing them through molten material, preferably molten lead covered by a layer of molten zinc chloride, the hydrocarbons being caused to pass horizontally through the molten material, the latter has only a small free surface where the vapours are discharged and the vapours are passed through the bath at such speed that any carbon formed is carried away. The cracking vessel comprises two horizontal pipes 11, 12 jointed bv vertical pipes 13, 14. Molten metal is supplied from an inlet 15, and the cracked vapours pass off through a dome 4. The process is only applicable directly to hydrocarbons containing a small proportion of carbon and forming no liquid or heavy cracking residue. Hydrocarbons containing a large proportion of carbon receive a preliminary cracking in a similar apparatus in which the dome is divided by a partition 42, Fig. 3 transverse to the flow of vapour and by a partition 43 forming a lateral extension of the wall of the cracking chamber. Specifications 116,304, 141,223, 170,617 are referred to.

Filed: 1933-07-19
Abstract: 424,682. Machine guns. VICKERS-ARMSTRONGS, Ltd., LARSSON, C. A., and HIGSON, P. R., Vickers House, Broadway, Westminster. July 19, 1933, No. 3568 /35. Divided out of 424,630. [Class 92 (ii)] Relates to cartridge-feed mechanism, more particularly for belt-fed guns of the Vickers type, of the kind in which upper and lower levers J<2>, J for reciprocating the feed-slide B, are mounted on a pivot pin j passing through the feed-box A. Such cartridge feed mechanism has previously been made reversible for right or left hand feed by providing a reversible feed-box and alternative apertures in the feed-box to receive the pivot pin j. According to the present invention the apertures j<1> , j<2>, are arranged on opposite sides of a line drawn longitudinally of the gun so that reversal of the whole feed - box is unnecessary. T o effect the reversal of feed, the pivot pin j, the upper lever J<2>, the feed-slide B, the cartridge guide and stop H, the bullet-stop K and the double-feed preventing pawl E, Fig. 5, are removed. The parts are then reassembled in reverse position as partly shown in Fig. 3, after the feed-slide carrying the feed-pawl D has been reversed in the feed-box. The pivot pin passes through a hole h<1> in the cartridge guide and stop H which is further held in position by a pin h<3>. The pairs of retaining-pawls F<1>, F<2> are duplicated, each pair being cross-connected by finger release bars f<4>, f<2>. Specification 424,630 is referred to.

Title: Improvements in weighing apparatus for loading predetermined quantities of materialsinto sacks or the like
IPC: B65B1/34
Filed: 1959-02-02
Abstract: 916,036. Automatic feed weighers. COMPAGNIE DE SAINT-GOBAIN. Feb. 2, 1959 [Jan. 31, 1958], No. 3677/59. Addition to 841,850. Class 143. The fluid-pressure controlled sack-filling automatic feed weighing apparatus of the parent Specification, is provided with a weighing receptacle having a closable outlet, which receptacle may be used in substitution for the sack holder. The receptacle comprises a hollow rigid casing 63a having a tapered lower portion 63a to which the outlet-a flexible sleeve 63dis attached, the outlet being closable by members 64a operated by mechanism 65, which is the same as the clamp-operating mechanism of the sack holder described in the parent Specification. Pressure from the control system may be applied to the mechanism 65 as shown in Fig. 5, by connecting it via a pipe 83 to a cylinder 68. The latter contains a piston 71 which is moved to the left by pressure applied to inlet 81 when a manually operable valve 72 is actuated at the commencement of a weighing, the feed to the weighing receptacle being initiated by the opening of cock 103 by lever 90 at the end of the leftward stroke of piston. During this movement a pressure inlet at 85 causes pipe 83 to be pressurized to close the outlet members 64a and, on actuation of cock 103, stop member 69 is actuated to descend to the position shown and prevent return movement of piston 71 during the weighing so that the receptacle outlet remains closed. When the weighing is completed, the catch 67 is automatically released, piston 71 moves to the right under pressure from inlet 85, the pressure at inlet 81 having been stopped by the previous release of valve 72. At the end of this rightward movement the piston abuts stop 70 and pressure in line 82 operates a beam locking member 40 (c.f. Fig. 9 of parent Specification). The operation of the latter pressurizes line 66 so that a cover plate 75a, which has hitherto covered a valve 73, is moved by piston 75 to the right. Valve 73 may now be manually operated to release catch 70 when the piston will complete its rightward movement, in so doing de-energizing line 83 and releasing the receptacle outlet control mechanism 65 to discharge the weighed load. The discharge may be made automatic by dispensing with the cover plate 75a and instead causing pressure in line 66 to operate mechanism 65 directly.
